title: Ganoderic acid Me inhibits tumor invasion through down-regulating matrix metalloproteinases 2/9 gene expression.
abstract: The effect of ganoderic acid Me (GA-Me), which was purified from the fermentation mycelia of the traditional Chinese medicinal mushroom Ganoderma lucidum as reported (Tang W, Gu TY, Zhong JJ. Biochem Eng J. 2006;32:205-210), on anti-invasion was investigated. Wound healing assay indicated that GA-Me inhibited cell migration of 95-D, a human highly metastatic lung tumor cell line, in dose- and time-dependent manners. Results of cell aggregation and adhesion assays showed that GA-Me promoted cell homotypic aggregation and inhibited cell adherence to extracellular matrix (ECM). In addition, GA-Me suppressed matrix metalloproteinases 2/9 (MMP2/9) gene expressions at both mRNA and protein levels in 95-D cells according to qRT-PCR and Western blotting, respectively. The results demonstrated that GA-Me effectively inhibited tumor invasion, and it might act as a new MMP2/9 inhibitor for anti-metastasis treatment of carcinoma cells.
